Uh, Fleexy, you wouldn't mind if you could please tell how to import NetKeen levels with Abiathar? I tried doing that by using level and graphic files in the NetKeen Modding and Leveling Package, and this is what the results looked like (I'm viewing the Border Town map):

Sorry for the confusion; that guide is pretty old. As of v2.0, you can simply use the NetKeen profile found in the New Project Wizard. Then, instead of using the stuff from the Modding and Leveling Package, just open the CKV files from the normal download's "game" folder. Make sure you handle tileinfo as part of the map header. This approach works for me on the data from the wiki's NK:V download link. The first level (world map) is garbage; that's normal. I would upload an image of it working, but Imgur seems to be experiencing interruptions.

Well, I managed to figure out a way to properly import NetKeen levels. Thanks, Fleexy! Though, when checking out the level list, I found another problem. The list can't go beyond level 36, which means that there is no way get to level 37 and onward without creating a new level in their place (unless I missed something).

NetKeen might have an upper limit less than the normal 99; I don't remember for sure. You can add a new level to the level set with Level | Add, or duplicate an existing one with Level | Copy. If NetKeen doesn't see a level beyond a certain ID, you'll need to overwrite a lower-numbered one. You can renumber a level in the Level | Properties window.

Bug Report:Abiathar constantly crashes when trying to generate patches for a KDreams mod. the aerrl file states that it couldn't find KDRPATCH.EXE.
side-note: the machine I'm running Abiathar in has no internet connection.

Oops, this bug affects patch generation for all games. You can work around it by placing a file - any file, even an empty one - called KDRPATCH.EXE (or the appropriate patching program) in the project folder. In fact, you can get the right one out of the File Emitter. This should be pretty easy to fix; I'll get on that.

This should be fixed now. Thanks again!

UPDATEv2.8.8: fixed patch generator and performance improvements

The patch generator now correctly determines whether it needs to add or replace a patching executable.

Performance should be even better now - the ancient event bus system (literally untouched since v1.0) has finally been rewritten. It now only searches for event handlers once, after extensions are loaded. Existing extensions should see no change. Additionally, some unnecessary value type boxing-unboxings have been removed.

The background tiles don't have any effect; that plane is only cosmetic. There are invisible foreground tiles that provide the "door" behavior. In Keen 6, you need tile 0401h (1025 in decimal). You can check whether you have the right one by enabling the Tile Properties overlay and showing the Door special property in the "tileinfo overlay settings" window: a D will appear over door tiles.
